Product Marketing Studio

Overdrive helps B2B SaaS scale-ups structure their Product Marketing and Go-To-Market through fractional leadership, not execution-for-hire.

I step in as a Fractional Product Marketing Leader to clarify positioning, align Product, Marketing & Sales, and secure sustainable growth, especially during scale-up and international expansion phases.

→ Fractional leadership. Real impact. No full-time hire.

Who this is for

Overdrive works with B2B SaaS scale-ups that have traction, and are starting to feel friction.

You’re a good fit if:

  • You’re between 50 and 200 people

  • Growth is real, but messaging and GTM are getting messy

  • Product, Marketing and Sales are not fully aligned

  • You’re scaling fast, expanding internationally, or preparing the next growth phase

You need senior Product Marketing leadership, without rushing a full-time hire

When teams usually call Overdrive

Most clients reach out when at least two of these signals are already visible:

  • Your go-to-market exists, but feels chaotic or fragile

  • Positioning and ICP are unclear or debated internally

  • Sales messaging varies from one rep to another

  • Product decisions lack strong market or competitive inputs

  • International expansion (EU / US) underperforms expectations

  • Your PMM function lacks clear leadership or cadence

If growth is starting to expose cracks, this is usually the right moment.

What I actually fix

Overdrive addresses structural problems, not surface symptoms.

  • A go-to-market that doesn’t scale

  • A positioning that tries to speak to everyone

  • Weak or inconsistent messaging

  • Poor market, competitive or win-loss insights

  • Friction between Product, Marketing and Sales

  • Sales enablement that looks good but doesn’t help sell

  • PMM teams executing without direction or ownership

  • International expansion handled by “translation, not adaptation”

What you get instead

By the end of the engagement, clients typically gain:

  • A clear, prioritized go-to-market

  • A strong positioning and ICP definition

  • A messaging framework actually used by Sales

  • Better alignment across Product, Marketing and Sales

  • A structured Product Marketing cadence

  • A PMM function that can scale — with or without me

  • A safer path to EU / US expansion

This is about clarity, discipline and leadership — not more activity.

Engagement options

Interim PMM — Continuity & Transition

  • set up and upskill the PMM function

Ideal for scale-ups that need leadership, not execution support.

6 months

For companies facing high-stakes growth or international expansion.

  • positioning adaptation per geography

  • international sales enablement

  • CEO / C-level advisory on GTM decisions

Designed for long-term impact, with built-in commitment and de-risking.

What Overdrive is not

Overdrive is not a fit if you’re looking for:

  • a pure execution resource, like just writing content

  • short-term “lead generation fixes”

  • a PMM doing tickets without mandate

  • a role without decision power

  • heavy micromanagement or low-trust environments

Fractional leadership only works with clarity, trust and ownership.

  • "I was fortunate to have Sébastien on my team at Woop. He created the Product Marketing function there. He successfully implemented numerous tools and methodologies: sales enablement, competitive intelligence and analysis, product launches, offer packaging, etc. Sébastien is a true team player, pleasant and fully committed."

    Matthieu – CMO Woop

  • "What impressed us most was how well they listened and took care to rephrase our requirements to ensure they were met perfectly. Although this approach is central to this type of project, it was executed particularly well, making the collaboration experience very pleasant and effective."

    Pierre – CEO EdTEch platform

  • "The scope and depth of the report exceeded our expectations. I have only positive feedback on the work accomplished, the quality of the deliverables, and the communication throughout the project. Excellent work!"

    Josh - CEO E-commerce platform

About

I’m a senior Product Marketing leader with nearly a decade of experience in B2B SaaS, complex products and international environments.

I’ve worked inside scale-ups and as a fractional leader, helping teams move from activity to clarity, and from growth by effort to growth by structure.

Overdrive is the result of that experience, focused, opinionated, and built for impact.
